Justin Bieber and Selena Gomez just can't seem to stay away from each other. A month after their most recent breakup, the on-again/off-again couple reunited in L.A. for the first time since their huge, relationship-ending fight in Puerta Vallarta, Mexico.

The Spring Breakers actress, 20, was photographed leaving Bieber's house early on the morning of Feb. 2, reportedly after staying the night. Dressed in a yellow cardigan, black pants, and a black hat, the starlet was escorted home -- suitcases in tow -- by one of her ex-boyfriend's drivers.

Though Gomez's face is not visible in the pictures, a source confirms to Us Weekly that the former lovebirds did indeed see each other. It's unknown, however, whether their reunion was romantic in nature.

Indeed, the back-and-forth between the two is constant. In the month after their late-December breakup, both stars made cryptic references to the roller-coaster that has been their relationship over the last two years. Gomez coveredJustin Timberlake's famous kiss-off anthem "Cry Me a River," telling fans the tune "definitely spoke to her," while Bieber responded in kind with a song of his own, "Nothing Like Us."

"It tells the whole story" of their breakup, a source told Us of the ballad, one of three new tracks from the 18-year-old singer's recently released Believe Acoustic album. "This is his answer to Selena."
